PICK.

SPECIFICATION forming part of' Letters Patent 1\ l'o. 255,533, datedMarch 28, 1882.

Application filed December 7, 1881.

To all whom it may concern:

Be it known that I, EBENEZER R. RAY, of Bodie, county of Mono, State ofCalifornia, have invented an Improvement in Picks; and I hereby declarethe following to be afull, clear, and exact description thereof,reference being bad to the accompanyingdrawings, making part of thisspecification, in which- Figure 1 is a perspective view of my improvedpick. Fig.2 is alongitudinal sectional view of the same.

My invention relates to the class of picks and to those in which thepoints are adapted to be easily fitted to and to be removable from thestock.

It consists in the novel construction of the stock and points withcorresponding shoulders and sockets, whereby the latter may be readilyand securely fitted to the former, all of which will hereinafter morefully appear, reference being made to the accompanying drawlugs.

The object of my invention is to provide a pick the points of which maybe easily removed when dull and others substituted.

In all mines picksbecome dull very readily, and have to be sent totheshop to be sharpened so frequently that a great deal of time is lost bythe miner who is working at considerable depth in securing another. Thisnecessitates having a large supply of picks on hand;

but by having the points removable a number of them may be carried bythe miner to his work, and when one becomes dull another can beimmediately substituted.

Let A represent the stock, having an eye, B, in which the handle isadapted to lit. The outer ends of the stock are provided with or formedinto projections or tongues a. a, and on their under sides, which areinclined, as shown at m, have grooves b b, with projecting under lips, c0. 1

G 0 represent the points. Their innerends are formed into tongues e e,and have shouldersff. Their upper sides, n, are oppositely inclined tothe under sides of the stock, and

(No model.)

terminate in a shoulder, g, in which is a socket, it. Their outer endsare curved to a point, as shown. Screw-holes D through the pointscorrespond with the holes (1 d in the stock.

In fitting the point to the stock the inclined sides on and a of thestock and point lie together, the tongue 0 fits into the grooves b, andthe lip c abuts against the shoulder f. The tongue a upon the end of thestock: fits into the socket h in the point, and the end of the stockabuts against the shoulder Screwbolts E E are put through the holes D d,and thus the points are secured firmly and rigidily to the stock.

For the sake of convenienceI make a groove, F, in the side of thepoints. This groove enables me to use the point when removed, or anextra point, as a wrench to remove the screwbolts and take oil thepoint. The groove Fis made of a sizeito fit the heads of the screwbolts.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The pick-stock A, theends of which have the tongues a and the undersides, m, inclined, terminating in grooves b, with lips 0,1incombination with the points 0, having sockets h 'and shouldersg,inclined upper sidesm, tongue e, and shoulders f, said stock andpoints being fitted together and secured by screw-bolts E E,substantially as and for the purpose herein described.

2. In a pick the points of which are independent of the stock andadapted to be secured thereto by screw boltsE E, as herein described,the groove F, formed in the sides ofsaid points, whereby said points maybe used as wrenches to remove said screw-bolts, substantially as and forthe purpose herein described. I

In witness whereof I hereunto set my hand.

EBENEZER ROSS RAY.
